New high temperature process to decarbonise greenhouse gas directly to diesel fuel

In 2016 South Korean researchers  developed a new catalyst to modify a long established gas to liquid process.

The new delafossite catalyst promises a two-fold benefit, removing harmful CO2 from the atmosphere while producing diesel.

Here is the link to the promotional press release.

The Fischer–Tropsch process is widely used to convert a mixture of CO and hydrogen into liquid hydrocarbons.

This is different to the German car maker Audi’s CO2-to-diesel conversion process, which actually involves two steps: reverse water gas shift reaction to CO followed by the conventional Fischer–Tropsch synthesis.

The Fischer Tropsch feed is usually syngas, which can be produced by steam reforming of methane, possibly sourced from biomass via anaerobic digestion by the following reaction:

CH4 + H2O ⇌ CO+ 3H2

Syngas can also be produced by gasification of biomass or fossil fuel based carbonaceous materials, usually in a fluid bed reactor.

The water gas shift reaction is a metal catalysed reaction that also occurs at high temperatures concerning the reaction:

CO + H2O ⇌ CO2 + H2

These processes and reactions important in the broad area of Carbon Capture and Storage as they can remove green house gases from the atmosphere and to Biorefineries.
